| Abstract: | Starting from the magneto-hydrodynamic(MHD) equations,the computing formulas for magnetic anomaly induced by underwater vehicle's motion in geomagnetic field have been derived by use of order analysis.The computing method has also been given.As an example,the order of magnetic anomaly induced by the wake of propeller-driven body has been estimated. |
